GPX Route Map

No. It has no plugin dependencies and works with core WordPress.

Map rendering uses MapLibre GL JS (BSD-3-Clause) with OpenStreetMap raster tiles. The track, elevation profile and the distance/elevation stats are all computed from your GPX file in the browser. When you add the block, those stats are saved with it so the summary still shows without JavaScript.

Yes, set a custom tile URL in the block's Map tiles panel or with the gpxrm_tile_url filter.

Only if that host allows cross-origin (CORS) requests, because the visitor's browser fetches the file directly, and most external sites don't send the required header. The front end then shows "Could not load GPX file." even though the link opens fine in a browser tab. Uploading the file to your Media Library is the reliable option.

GPX files uploaded before this plugin was activated may be stored with a generic XML type or no type at all. The picker shows GPX and XML types; files stored with an empty or unrelated type won't appear. Re-upload them to fix the stored type. On multisite, the network's "Upload file types" setting must also include gpx.

The map library could not be downloaded. The plugin loads its map code as a native JavaScript module, which optimization plugins normally leave alone. But if yours is configured to combine, inline or relocate module scripts, exclude this plugin's view script from it. Visitors on a flaky connection can simply click the message to retry.
